To all whom zi may concer-12,.'

Be it known that we, FRANCIS REYNOLDS and WILLIAM JOSEPH UNDnRWooD, citizens of the United States, andl residentsof 4Fall River, in the county of Bristol and State of.

visable to refer brieiiy to'the well-knownstrueture of a mule of the kind commonly used. In the accompanying drawings like figures indicate like parts in all the views.

Figure 1 is aside elevation of a mule, showing certain parts broken away and certain details in section. Fig. 2 is a section uponthe line 2 2 of Fig. 4 looking in the'dire'ction of the arrows. Fig. 3 is a detail section upon the line 3 3 of Fig..2 looking inthe direction of the arrow. Fig.4 is an end elevation showing the parts as seen by an observer standing to the right of Fig. 2, and Figs. 5 and 6 are details of the shifting rod and various appurtenances. e

Upon the bed-frame l, which is of the usual pattern, is mounted the framework 2 2 3 3, which carries the bulk of the machinery. Upon the overhead shaft 4 are mounted pulleys 5 6, provided with suitable belts, as 7, which cause rotation of the pulleys 8, 9, 10, and 20. From these pulleys 5 and 6 are drivenV pulleys 8, 9, 10, and 20, 9 being an idle or loose pulley. The clutch members 11 are caused to grip'fand release by the clutch-collar 12,'which is actuated bya series of levers 12', these being in turn'actuated by the rod 39', to which the sickle 38' is attached in the usual manner. By means of gear-wheels 13 14 15 and agrotary shaft 16 motion is communicated to the bevel-gear 17', thereby causing rotation of the vscroll-drum 17, upon which runs the rope 18 for the purpose of moving the carriage outward in the usual manner.l To move the carriage inward, the scroll-drum I 19 is provided with arope 19', secured directlyV to the carriage. By means of the clutch 20' power is applied to the scroll-drum.

The shiftingarm is shown at 21, the shifting rod at 22, the shifting spring at 23, the shifting dog at 24, and the shifting lever at 25, the

same being pivoted upon the shaft 27 and provided with a hook 26. A fixed boss 28 is secured in the end of the cam-like track 28' for the purpose of disengaging the boot-leg 6o by tripping the hook 30 secured thereto,which tripping is accomplished by the movement of the carriage toward the left. are mounted free to reciprocate vertically,

the lower ofthese rollers directly engaging 'the surface of the cam-like track 28.

In Fig. 1 the carriage lis represented as l partly broken away, the -wheel 32, frame 33, and other parts being of the usual pattern.

`Mounted upon the carriage is a bell-crank 34, 7o

provided with two members, one beingpthe swanneck 34' and the other being'the upwardly-projecting arm 32'. The link 35 connects this upwardly-projecting arm with the boot-leg 29., The faller is shown at 36, the 7'5 horseshoe at37 Thesepa'rts. are VIpivotally mounted upon the faller-shaft 37', which is in turn mounted upon the bracket 38, the same being secured to the carriage and movrable therewith. The sickle is shown at 38', 8o 'being connected with the rod 39' for the purpose of actuating the clutch 11, as above described. The vertically-reciprocating member 39, whichI we style a .jumperf does not movewith the carriage, but is mounted upon pose of raising and lowering the quadrant 40,' 9o

as shown more particularly inFig. 4.

The rod 43is connected with the rod 22 by means of a fastening 22' in'such a manner that the tension of the spring 23 is normally in a direction tending to move the rod 43 to- 95 ward the left when the apparatus is seen` as in Fig. 2. When the carriage slides to the left, the faller-shaft 37' strikes the lever 25, raising the hook 26 and releasing the dog 24,-

which allows the shifting rod 22 to move to Ioo The rollers 3l I the right, thereby relinquishing the tension of the spring 23. This of course releases the clutch 2O and places the carriage in a position to be moved back again to the righthand side of the frame-that is, to assume the position shown in Fig. l. lVhen the carriage is in the position shown in Fig. l, however, the tension of the spring 23 is upon the shifting rod 22, the spring being held in a compressed position by means of the hook 2G. The tendency of the spring, therefore, is to move the rod 43 to the left, thereby exerting tension upon the lever 44, which, however, is prevented from moving in the direction indicated by the boss 45, which is held down by the notch 46 in the lower part of the lever 5l, as shown more particularly in Fig. 2. Thislever 5l is moved,however, and the notch 46 released from the boss 45 by the head 35, mounted upon the carriage, pressing into engagement with the bolt 53, causing the lower part of the lever 5l to swing to the right. The boss 45 being thus disengaged, the shaft 52 rocks to the left, thus raising the shaft 5l and the jumper 39, which is guided by means of a slot 4S, through which passes the bolt 49, secured upon the stationary bracket 50, and is thus kept in position. This movement takes place as the carriage starts to move toward the left and is technically designated as moving in and causing the swanneck 34 to pull oft the roller 59-that is to say, the mere disengagement of the boss 45 from the notch 46 of the lever 5l is not alone sufficient to cause the jumper 47 to rise, because the same is held down by the swanneck 34. When, however, the carriage starts in, the swanneck 34 by pulling off from the top of the roller 59 leaves the jumper entirely free and under the tension of the spring 23, as above described, the 'jumper suddenly rises.

All of the above parts are old, together with the crank 57, link 53, and cranks 55 5G, connecting the rod 22 with the shaft 57. By the travel of the carriage inward and outward, therefore, the jumper is alternately depressed by the swanneck and allowed to spring upward upon being released thereby.

The function of the jumper 39 is to release the rod 43, thus allowing said rod to press the lever 21 toward the left, and thereby cause the clutch members 2O 20 to grip. This movement can be understood by inspection of Figs. 2 and 5. The normal tendency of this rod 43 under the tension of the spring 23 is to cause said clutch members to grip. When the swanneck 34 leaves the roller 59, the sudden release of the rod 43 causes the clutch members 2O 20 to close with a sudden snap, thus throwing undue strain upon the framework and moving parts. The upward curve of the swanneck slightly retards the release of the jumper, and consequently retards the movement of the rod 43, thus in a measure lessening the shock; but additional means for cushioning the shock are v ery desirable.

Our invention consists in means for cushioning the effect of the part which we style the jumper as it moves abruptly upward, the part itself being old. To this end we provide a large roller 54 upon the shaft 51 and also provide a composite adjustable lever for the purpose of engaging this roller, and thereby cushioning its upstroke. The lever in question consists of three members G2, GG, and 67. The member 67 is curved and the end G6 rests upon the reciprocating rod 70, which slides through brackets 72 and 73 and engages a spring 7l by means of the collar 7l. The lever is normally in the position shown in Fig. 2. By means of the bolts 68 69 the lever can be lengthened or shortened, as desired. By lengthening and shortening the lever, more particularly the curved end thereof, the upstroke or thrust of the jumper can be materially modified, as the roller 54 is thus made to strike a different part of the curved end 67, and therefore to strike the same at slightly-different angles. An adjustable disk 6l is provided with a boss G3 and with a thumbnut 64, which engages the washer 65, and thereby secures the disk Gl in any desired radial position. The object of making the disk 6l radially adjustable is to place the boss G3 in any radial position within reasonable limits for the purpose of acting as a stop for the composite lever above described. In the position shown in Fig. 2 the spring 7l, pressing upward against the inner end of the lever, causes the lever to engage the boss 63, and this limits the downward play of the curved section G7 toward the roller 54. It will be seen, therefore, that by adjusting the position of the disk 61 the lever can be set so as to normally rest at any desired angle and the end G7 can be brought into close proximity to the roller 54 or raised some distance therefrom. By means of this adjustment and the adjustment due to the bolts G9, together with the curvature of the end G7, the cushioning effect of the lever upon the roller 54 can be modified in several diierent ways.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. An apparatus of the kind described, comprising a jumper, a revoluble member connected therewith, and a buffer engaging said revoluble member for the purpose of cushioning the upthrust of said jumper.
